Passage Three
Questions 31 to 35 are based on the following passage.
In the late 1960's many people in North America turned their attention to environmental problems，and new steel-and-glass skyscrapers(摩天楼)were widely criticized. Scientists pointed out that blocks of tall buildings in a city often overburdens. public transportation and parking lot capacities.
Skyscrapers are also big consumers，and wasters，of electric power. In one recent year. the addition of 17 million square feet of skyscraper office space in New York City raised the peak daily demand for electricity by 120，000 kilowatts-enough to supply the entire city of Albany，New York，for a day.
Glass-walled skyscrapers can be especially wasteful. The heat loss(or gain)through a wall of half-inch plate glass is more than ten times that through a typical brick wall filled with insulation board. To lessen the strain on heating and air-conditioning equipment，builders of skyscrapers have begun to use double-glazed(装上玻璃的)panels of glass，and reflective glasses coated with silver or gold mirror films that reduce glare as well as heat gain. However. mirror-walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings.
Skyscrapers put a severe strain on a city's sanitation(卫生)facilities，too. If fully occupied, the two World Trade Center towers in New York City would alone generate 2.25 million gallons of raw wastes each year-as much as a city the size of Stamford，Connecticut，which has a population of more than 109，000.
Skyscrapers also interfere with television reception，block bird flyways，and obstruct air traffic. In Boston in the late 1960's，some people even feared that shadows from skyscrapers would kill the grass on Boston Common.
Still，people continue to build skyscrapers for all the reasons that they have always built them-personal ambition(抱负)pride，and the desire of owners to have the largest possible amount of rentable space.
The main purpose of the passage is to______.
A. compare skyscrapers with other modem structures
B. describe skyscrapers and their effect on the environment
C. advocate the use of masonry(化妆舞会)in the construction of skyscrapers
D. illustrate some architectural designs of skyscrapers

根据下列文章，回答31～35题。In the early 1960s Wilt Chamberlain was one of only three players in the National Basketball Association （NBA） listed at over seven feet. If he had played last season, however, he would have been one of 42. The bodies playing major professional sports have changed dramatically over the years, and managers have been more than willing to adjust team uniforms to fit the growing numbers of bigger, longer frames.The trend in sports, though, may be obscuring an unrecognized reality: Americans have generally stopped growing. Though typically about two inches taller now than 140 years ago, today''s people- especially those born to families who have lived in the U.S. for many generations- apparently reached their limit in the early 1960s. And they aren’t likely to get any taller. In the general population today, at this genetic, environmental level, we''ve pretty much gone as far as we can go, says anthropologist William Cameron Chumlea of Wright State University. In the case of NBA players, their increase in height appears to result from the increasingly common practice of recruiting players from all over the world.Growth, which rarely continues beyond the age of 20, demands calories and nutrients–notably, protein–to feed expanding tissues. At the start of the 20th century, under-nutrition and childhood infections got in the way. But as diet and health improved, children and adolescents have, on average, increased in height by about an inch and a half every 20 years, a pattern known as the secular trend in height. Yet according to the Centers for Disease Control and Prevention, average height- 5′9〞for men, 5′4〞for women- hasn''t really changed since 1960.Genetically speaking, there are advantages to avoiding substantial height. During childbirth, larger babies have more difficulty passing through the birth canal. Moreover, even though humans have been upright for millions of years, our feet and back continue to struggle with bipedal posture and cannot easily withstand repeated strain imposed by oversize limbs. There are some real constraints that are set by the genetic architecture of the individual organism, says anthropologist William Leonard of Northwestern University.Genetic maximums can change, but don''t expect this to happen soon. Claire C． Gordon, senior anthropologist at the Army Research Center in Natick, Mass, ensures that 90 percent of the uniforms and workstations fit recruits without alteration. She says that, unlike those for basketball, the length of military uniforms has not changed for some time. And if you need to predict human height in the near future to design a piece of equipment, Gordon says that by and large, you could use today’s data and feel fairly confident.第31题：Wilt Chamberlain is cited as an example toA．illustrate the change of height of NBA players.B．show the popularity of NBA players in the U.S……C．compare different generations of NBA players.D．assess the achievements of famous NBA players.

Passage ThreeQuestions 31 to 35 are based on the following passage.An understanding of man's effect on the balance of nature is crucial (关键的) to being able to find the appropriate remedial action. It is a very common belief that the problems of the population explosion are caused mainly by poor people living in poor countries who do not know enough to limit their reproduction. This is not true. The actual number of people in an area is not as important as the effect they have on nature. Developing countries do have an effect on their environment, but it is the populations of richer countries that have a far greater impact on the earth as a whole.For example, tropical forests are known to be essential to the balance of nature, yet we are destroying them at a great rate. They are being cleared not to benefit the natives of that country, but to satisfy the needs of rich countries. Central American forests are being destroyed for grassland to make pet food in the United States cheaper; in Papua slew Guinea, forests are destroyed to supply cheaper cardboard packaging for Japanese electronic products; in Burma and Thailand, forests have been destroyed to produce more attractive furniture in Singapore and Hong Kong. Therefore, a rich person living thousands of miles away may cause more tropical forest destruction than a poor person living in the forest itself.In short, it is everybody's duty to safeguard the future of mankind—not only through population control, but by being more aware of the effect his actions have on nature. Nature is both fragile and powerful. It is very easily destroyed; on the other hand, it can easily destroy its most dangerous enemy—man.31.According to the first paragraph, people usually believe that .A.poor people in poor countries contribute to the imbalance of natureB. rich people know how to protect the environment by taking actionsC. people in poor areas know a lot about the birth controlD. rich people in rich countries have done a lot to balance nature
